Research direction
Start with the CodePen reproduction and compare layer.addGeometry(Geometry) with layer.addGeometry([Geometry]) while changing the pitch for geometry larger than a hemisphere. Trace the vector geometry rendering path responsible for this difference; done means the single-geometry case no longer jitters or changes shape during pitch changes, matching the array case.
